The development of efficient multimodal interfaces and fusion algorithms requires knowledge of usage patterns that show how people use multiple modalities. We analyzed multimodal usage patterns for TV-guide application scenarios (or tasks). In order to collect usage patterns, we implemented a multimodal usage pattern collection system having two input modalities: speech and touch-gesture. Fifty-four subjects participated in our study. Analysis of the collected usage patterns shows a positive correlation between the task type and multimodal usage patterns. In addition, we analyzed the timing between speech-utterances and their corresponding touch-gestures that shows the touch-gesture occurring time interval relative to the duration of speech utterance. We believe that, for developing efficient multimodal fusion algorithms on an application, the multimodal usage pattern analysis for the given application, similar to our work for TV guide application, have to be done in advance.

Knowledge based system includes tools for constructing, testing, validating and refining the system along with user interfaces. An important issue in the design of a complete knowledge based system is the ability to produce explanations. Explanations are not just a series of rules involved in reasoning track. More detailed and explicit form of explanations is required not only for reliable reasoning but also for maintainability of the knowledge based system. This requires the explanation mechanisms to extend from knowledge oriented analysis to task oriented explanations. The explicit modeling of problem solving structures is suggested for explanation generation as well as for efficient and effective reasoning. Unlike other explanation scheme such as feedback explanation, the detailed, smaller and explicit representation of problem solving constructs can provide the system with capability of quality explanation. As a key step to development for explanation scheme, the problem solving methods are broken down into a finer grained problem solving primitives. The system records all the steps with problem solving primitives and knowledge involved in the reasoning. These are used to validate the conclusion of the consultation through explanations. The system provides user interfaces and uses specific templates for generating explanation text.

This paper has investigated the cultural practices influencing business performance and integrity in selected Malaysian contractors and has discussed culture related issues to improve the management of cultural capitals in the Malaysian construction industry. Issues of current enterprise culture and applicable cultural practices, leadership styles, enterprise axiology and integrity, cultural practices and loyalty, and identification of organizational culture are discussed during the semi-structured interviews and questionnaire survey. Conclusions has been drawn that the people oriented and task oriented management style have a similar quantity of supporters in Malaysian contractors. The integrity and profit are respectively identified as the enterprise axiology in the ethical and economic perspective. The monkey culture is considered as the most applicable type for the cultural practice and the current enterprise cultures applied in the Malaysian contractors are mostly positive to both the organizations and society.

Purpose - This study explores the causes behind the high rate of impulse purchases in live streaming e-commerce. Design/methodology/approach - The research model is empirically validated with survey data collected from 324 respondents in China, using the Partial Least Squares (PLS) methodology. Findings - We found that the interactivity and visibility of live streaming are key in creating para-social relationships and perceived presence, leading to customers' impulse purchases. Research implications or Originality - This study deepens the understanding of consumers' impulse purchases in live-streaming e-commerce, revealing that para-social relationships and perceived presence developed through real-time interactions can increase impulse buying. It also highlights the differences between relationship-oriented and task-oriented interactions in fostering customers' perceived presence and para-social relationships in live streaming.

Purpose : This research is, by investigating the relations between the cultural types of a nursing organization in a hospital and performance, to ascertain the cultural types to be able to improve performance. Method : The data were gathered from 487 nurses and 328 patients who were in eight general hospitals by using the self-report type of questionnaires. The period of data collection was from August 10, 2000 to September 10, 2000. For this research, the following tools were used; the tools for measuring the organizational characteristics, organizational culture, and job satisfaction, the tool for measuring organizational commitment, and the tool for measuring patients' satisfaction. For data analysis the SPSS Win 7.5 program was used. Result : 1) There was a significant difference in the organizational culture type according to the establishment type of hospital. 2) In the relationship between organization characteristics and organizational culture of a hospital were correlated with the type of each culture(p=0.00). 3) In the relation between the organizational culture type of hospital and its performance, there was a strong positive correlation between innovation-oriented culture and job satisfaction. And relation-oriented culture and task-oriented culture showed that they had a weak positive correlation with job satisfaction(p=0.00). There were a positive correlation between affective commitment and relation-oriented, innovation-oriented cultures(p=0.00), and there were no culture type significantly related to continuance commitment and there was a weak positive correlation among normative commitment and innovation-oriented culture, relation-oriented culture(p=0.00). 4) The types to have an influence upon nurses' job satisfaction were innovation-oriented culture and relation-oriented culture. These had 34.5% of influence with job satisfaction.. The type of organizational culture did not influence continuance commitment, but it had an influence on affective commitment and normative commitment. And relation-oriented culture and innovation-oriented culture had 21% of an influence with affective commitment, and they had 9.5% of an influence with normative commitment. Conclusion : As the above mentioned research results, the organizational culture type was found which had an influence upon nurses' job satisfaction and organizational commitment and patients' satisfaction in nursing service. These results are very significant in having showed the persons in charge of nursing administration a basic data for creation of an effective organizational culture.

Generally, development of a robot capable of fast movements or high payloads is progressed by the analysis of dynamic characteristics, DOF positioning, actuator selection, structure of links, and so on. This paper highlights the design of a robot manipulator handled by a human for man-machine cooperation. The requirements of the proposed system include its having multi-DOF(Degree of Freedom)and the capacity for a high payload in the condition of its maximum reach. The primary investigation factors are motion range, performance within the motion area, and reliabilityduring the handling of heavy materials. Traditionally, the mechanical design of robots has been viewed as a problem of packaging motors and electronics into a reasonable structure. This process usually transpires with heavy reliance of designerexperience. Not surprisingly, the traditional design process contains no formally defined rules for achieving desirable results, as there is little opportunity for quantitative feedback during the formative stages. This work primarily focuses on the selection of proper joint types and link lengths, considering a specific task type and motion requirements of the heavy material handling.
